Synthesis of NiFe2O4 nanofibers by joint sol-gel and electrospinning technique
(Belgrade : Association of Metallurgical Engineers of Serbia, 2018)
In this study, electrospinning combined with sol-gel technique is applied in order to produce magnetic nickel ferrite (Ni-ferrite) nanofibers. The prepared Ni-ferrite gel was mixed with poly(vinylpyrrolidone) (PVP) solution ...
Lovage (Levisticum officinale Koch.): Plant with great potential for use in organic agriculture / Selen (Levisticum officinale Koch.) - biljka velikog potencijala za primenu u organskoj poljoprivredi
(Poljoprivredni fakultet - Departman za zaštitu bilja i životne sredine "dr Pavla Vukasovića", Novi Sad, 2015)
Lovage (Levisticum officinale Koch.) is a perennial medicinal and aromatic plant from Apiaceae family. It is well established that lovage is a diuretic and expectorant, as well as that it has anticancerogenic and antioxidative ...
Effects of organically modified clay nanoparticles on the properties of poly(urethane-siloxane) nanocomposites / Uticaj organski modifikovanih naničestica gline na svojstva poli(uretan-siloksanskih) nanokompozita
(Serbian Chemical Society, 2016)
Series of poly(urethane-siloxane) nanocomposites (PUSN) was synthesized based on 4,4'-methylenediphenyldiisocyanate and 1,4-butanediol as the comonomers of the hard segments and
poly(propyleneoxide)-b-poly(dimethylsilo ...
The Morphological Characterization of Mechanically Activated ZnO Powder
(Belgrade : Serbian Ceramic Society, 2014)
The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces ...
Energy decomposition analysis of gauche preference in 2-haloethanol, 2-haloethylamine (halogen = F, Cl), their protonated forms and anti preference in 1-chloro-2-fluoroethane
(Royal Soc Chemistry, Cambridge, 2015)
2-Haloethanol and 2-haloethylamine (halogen = F, Cl) prefer gauche conformation. This preference is significantly increased upon protonation. Commonly used explanations are based on intramolecular hydrogen bonding and ...
Analysis of the Jahn-Teller effect in organic and inorganic systems / Analiza Jahn-Teller-ovog efekta u organskim i neorganskim sistemima
(Belgrade: Serbian Chemical Society, 2016)
The Jahn-Teller (JT) theorem states that a molecule with a degenerate electronic state spontaneously distorts along a non-totally symmetric vibrational coordinates. This removes the degeneracy and lowers the energy. The ...
Computational study of the spin-state energetics in manganese phthalocyanine
(COST Action CM1305Krakow, Poland : Faculty of Chemistry, Jagiellonian University, 2016)
Since 3d transition metal ion complexes in different spin states usually display quite different structural, spectral and magnetic properties, and also reactivity, it is important to correctly determine the spin ground ...
Hybrid Nd-Fe-B/barium ferrite magnetic materials with epoxy matrix / Hibdridni Nd-Fe-B/barijum-ferit magnetni materijali sa epoksi matricom
(Association of Chemical Engineers of Serbia, 2012)
Lately, there has been great attention paid to the research of bonded hybrid composites with improved dynamic mechanical capacities capable of replacing bonded Nd-Fe-B magnetic materials, by using cheaper (ferrite) materials ...
Plasmonic enhancement of photocatalytic optofluidic microreactors with corrugated thin metal films
(University of Belgrade - Institute of Chemistry, Technology and Metallurgy, 2017)
Plasmonics deals with electromagnetic waves that are bound to an interface between
conductor with free electron plasma and dielectric, and are evanescent in the perpendicular
directions. This ensures extreme localizations ...
Analysis of Reversible Adsorption in Cylindrical Micro/Nanofluidic Channels for Analyte Sensing and Sample Dilution Applications
(Beograd : Društvo za ETRAN / Belgrade : ETRAN Society, 2015)
The principle of operation of one class of chemical/biological sensors is based on adsorption of particles of a target substance from a fluid on a surface which can be a wall of a micro/nanochannel. When a channel is used ...
